fly ash

基本解釋

Canadian geologists have found evidence of coal char--"remarkably similar to modern coal fly ash" in their own words--in ancient Arctic rocks.
加拿大地質(zhì)學(xué)家們在古老的北極巖石中發(fā)現(xiàn)了煤炭的證據(jù)，“象極了現(xiàn)代的煤灰”這是他們的原話。
Given the toxic impact of modern coal fly ash on aquatic ecosystems, the scientists suggest that the massive coal conflagration may have created toxic marine conditions the world over.
現(xiàn)代的煤灰給水生態(tài)系統(tǒng)造成了有毒影響，科學(xué)家們表示，大量的煤炭燃燒也許已經(jīng)造成了全球范圍的有毒的海洋環(huán)境。
Other environmentally friendly bricks use fly ash, a byproduct of coal power plants, or even sand and urine.
目前還有一些其他材料制作的環(huán)保磚，如煤炭發(fā)電產(chǎn)生的飛塵，沙子甚至尿液。

Further, the coal is low on sulfur and fly ash content, which increases its attractiveness.
